Base Type¶

public Acts::SurfaceBounds (Class SurfaceBounds)

Class Documentation¶

class Acts::ConeBounds : public Acts::SurfaceBounds ¶

Bounds for a conical surface, the opening angle is stored in \( \tan(\alpha) \) and always positively defined.

The cone can open to both sides, steered by \( z_min \) and \( z_max \).

Public Functions

ConeBounds() = delete¶

ConeBounds(double alpha, bool symm, double halfphi = M_PI, double avphi = 0.) noexcept(false)¶

Constructor - open cone with alpha, by default a full cone but optionally can make a conical section.

Parameters

alpha: is the opening angle of the cone
symm: is the boolean indicating if the cone is symmetric in +/- z
halfphi: is the half opening angle (default is pi)
avphi: is the phi value around which the bounds are opened (default=0)

ConeBounds(double alpha, double minz, double maxz, double halfphi = M_PI, double avphi = 0.) noexcept(false)¶

Constructor - open cone with alpha, minz and maxz, by default a full cone but can optionally make it a conical section.

Parameters

alpha: is the opening angle of the cone
minz: cone expanding from minimal z
maxz: cone expanding to maximal z
halfphi: is the half opening angle (default is pi)
avphi: is the phi value around which the bounds are opened (default=0)

ConeBounds(const std::array<double, eSize> &values) noexcept(false)¶

Constructor - from parameters array.

Parameters

values: The parameter array

~ConeBounds() override = default¶

double get(BoundValues bValue) const¶

Access to the bound values.

Parameters

bValue: the class nested enum for the array access

bool inside(const Vector2 &lposition, const BoundaryCheck &bcheck = true) const final¶

inside method for local position

Return

is a boolean indicating if the position is inside

Parameters

lposition: is the local position to be checked
bcheck: is the boundary check directive

double r(double z) const¶

Return the radius at a specific z values.

Return

is the r value associated with z

Parameters

z: is the z value for which r is requested

double tanAlpha() const¶: Return tangent of alpha (pre-computed)

std::ostream &toStream(std::ostream &sl) const final¶

Output Method for std::ostream.

Return

is the input obect

Parameters

sl: is the ostrea into which the dump is done

BoundsType type() const final¶

Return the bounds type - for persistency optimization.

Return: is a BoundsType enum

std::vector<double> values() const final¶

Return the bound values as dynamically sized vector.

Return: this returns a copy of the internal values
